I've just developed a problem with an XJS that I'm rebuilding. It hasn't been on the road for a couple of years and tonight I took it out of the garage to turn it round so I could work on the other side. The o/s rear wheel was scraping across the road as I turned. I got it back in the garage and jacked one wheel up. I put it in drive with the engine running. The wheel off the ground turned slowly, and the wheel still on the ground turned too. Does this sound like a seized diff or could it be something else ?
